Remove/replace unnecessary logging.h includes in .cc files (headless)

CHECK, CHECK_EQ etc., and NOTREACHED/NOTIMPLEMENTED have moved
to the much smaller headers check.h, check_op.h, and notreached.h,
respectively.

This CL updates .cc files to use those headers instead when
possible, with the purpose of saving compile time.

notes on how the change was generated.)
